Abstract :
Uniform porous anodized aluminum oxide
(AAO) membrane has been synthesized by two-step
anodization for fabricating tungsten trioxide (WO3) nanowires. Under assayed conditions, uniform porous structure
of alumina (Al2O3) membrane with long range ordered
hexagonal arrangements of nanopores was achieved. The
self-assembled template possesses pores of internal diameter of 50 nm and interpore distance (dint) of 80 nm with a
thickness of about 80 lm, i.e., used for fabrication of
nanostructures. WO3 nanowires have been fabricated by
simple electroless deposition method inside Al2O3 nanopores. SEM images show tungsten trioxide nanowire with
internal diameter of about 50 nm, similar to porous diameter of AAO template. XRD results showed that nanowires
exist in cubic crystalline state with minor proportion of
monoclinic phase.
